NUT-LOCK.

Specification of Letters Patent.

Patented June 7, 1910.

Application filed. July 6, 1909. Serial No. 508,133.

To all whom it may concern:

Be it known that I, NATHANIEL J. Roenns, citizen of the United States, residing at Tuscaloosa, in the county of Tuscaloosa and State of Alabama, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification.

This invention relates to nut locks and has for its object to provide a comparatively simple and inexpensive device of this character for preventing accidental rotation of nuts on the securing bolts of rail joints, incident to the passage of cars and other railway rolling stock.

A further object of the invention is to provide a nut lock including a longitudinally disposed bar or bolt havin its intermediate portion bowed laterally ?or engagement with the adjacent fish plates and its opposite ends provided with loops or eyes terminating in threaded extensions which project through the adjacent rail sections for engagement with clamping nuts.

A further object is to provide an elastic track bolt or bar, the construction of which is such as to yieldably support the clamping nuts in contact with the fish plate, while at the same time permitting free expansion and contraction of the rails.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efiicienoy.

Further ob'ects and advantages will appear in the ollowing description, it being understood that various changes in form,

proportions and minor details of construction may be resorted to within the scope of the appended claims.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a front elevation of a rail oint provided with an elastic bolt or nut lock constructed in accordance with my invention; Fig. 2 is a longitudinal sectional view of the same; Fig. 3 is .a perspective view of the device detached; Fig. 4 is a longitudinal sectional view partly in section of a modified form of the invention; Fig. 5 is a perspective view of the device shown in Fig. 4 detached.

Corresponding and like parts are referred nary construction in which 5 designates the V abutting ends of adjacent rail sections, 6 the fish plates, and 7 the bolt receiving openings extending transversely through the fish plates and webs of the rail sections.

The device comprises an elastic bolt or bar preferably circular in cross section, as shown, and having its intermediate portion bowed laterally at 8 for contact with the ad jacent fish plate, and its opposite ends bent or coiled to produce loops or eyes 9 terminating in laterally extending shanks 10, which latter project through the bolt receiving openings 7 and are provided with exterior threads for engagement with suitable clamping nuts 11.

The base 12 of the loops or eyes 9 are A preferably spaced from the exterior face of the adjacent fish plate so that when the nuts 11 are adjusted on the threaded shanks 10, the spring loops 9 will exert a yieldable pressure on the clamping nuts and thus force the same in engagement with the fish plate, thereby to prevent accidental rotation of the nuts incident to the passage of cars and other railway rolling stock over the track.

The intermediate bowed portion 8, by engagement with one of the fish plates, not only serves to reinforce and strengthen said fish plate at the juncture of the rail sections 5, but also has a tendency to withdraw the threaded shanks 10 from the bolt receiving openings 7 when the nuts are adjusted on the threaded portions of the shanks, this spring action being supplemented by the loops 9. It will here be noted that the intermediate bowed portion 8 intersects both shanks 10 on the upper sides thereof so as to give a torsional twist to the bar or bolt at said loops, thus permitting the shanks 10 to move slightly on the intermediate portion of the bolt or bar when the nuts are adjusted. In using the device, threaded shanks 10 are passed through the bolt receiving openings 7 and the nuts 11 rotated with a wrench or other suitable tool until they bear against the adjacent fish plate. With the parts in this position, a further -rotary movement" imparted to the nuts will have a tendencyto contract the loops 9--andthen partially straighten out the intermediate bowed portion of the bar or bolt, thus effectually clamping the nuts against the adjacent fislf plate-and preventing accidental rotation of said nuts.

It willhere be noted that by forming the bar. with the springloops -9, .thethreaded shanks 10. of the 1 bar may be readily pressed together or apart so as tocauseqthe shanks to registerwith the bolt receiving-openings 'Zan'dthusxpermit the device to be. used on structures in which. the distance between the bolt-receivingopeningsvaries. It will struction and may be readilyformedfrom asingle length of. met-al thus materially-reducing" the costofmanufacturet 7 In Figs; 43 and 510i the drawings, there is illustrated a modified form of the invention in which thebar constituting the elastie, bolt is severed after 'theloop 9" is formed, .theend of them'eta'l'forming :the

7 loop being 1 extended laterally vbeyond the threaded shank 110 of the ,boltl'for contact with theflexterior'face of the adjacent fish plate, as shown. o

While the .device is. (principally designed for use asa railway track bolt, it will .of. course belunderstood. that thesame may be" used with e ually good resultofor securing the ,bolts of ridge work,-lbuilding cons'truc tions, or wherever. a. device of Qthis'character isffound desirable. l
